Interesting. I did not know about this.
It's disappointing that __resolve doesn't get any information as to
whether the property lookup is for a method call or not. I'm a little
hesitant to use that because it will be so different from the other
runtimes, and _possibly_ someone may have an application that relies
on using __resolve.
[I think that es4 was going to have something like a catch-all getter,
but it was dropped from 3.1/5, maybe it will be back in Harmony...]
